Head coach Bernard Jackman has left the Dragons after 18 months in charge. 

The former Ireland international was appointed in June 2017 and oversaw the team through a spell described by the Dragons on Tuesday as "transitional", as they managed just two Pro14 wins during his first season. 

There has been a slight improvement in results this term, with three victories in 10 league fixtures, but the club are now searching for a new coach. 

"I would like to place on record our gratitude to Bernard Jackman for his dedication and hard work in his role as head coach," said Dragons chairman David Buttress.

"Bernard has demonstrated his passion and commitment day in, day out on the training field. Away from first team affairs, he has been an asset to the Dragons in helping to promote our brand and rugby development at all ages throughout the region.

"Although this has been a difficult decision, we believe it provides us with the best opportunity to create future success on the pitch."
